In wireless LANs ( wireless local area networks), the hidden terminal problem is a transmission problem that arises when two or more stations who are out of range of each other transmit simultaneously to a common … WebCarrier-sense multiple access with collision avoidance (CSMA/CA) in computer networking, is a network multiple access method in which carrier sensing is used, but nodes attempt to avoid collisions by beginning transmission only after the channel is sensed to be "idle". When they do transmit, nodes transmit their packet data in its entirety. . It is …
WebA carrier sense multiple access with collision avoidance (CSMA/CA) is an access protocol of wireless LAN (WLAN). When the carrier sensing is missed, the WLAN systems simultaneously access the channel and then packet collision occurs. It is a hidden terminal problem.
